DATA SHEET
MOS INTEGRATED CIRCUIT
µPD78363A,78365A,78366A,78368A
16/8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
µPD78366A is provided with a high-speed, high-performance CPU and powerful operation functions. Unlike the
existing µPD78328, µPD78366A is also provided with a high-resolution PWM signal output function which
substantially contributes to improving the performance of the inverter control.
A PROM model, µPD78P368A, is also available.
Detailed functions, etc. are described in the following user’s manual. Be sure to read the manual to design systems.

I/O lines
Input 14 (of which 8 are multiplexed with analog input)
I/O 49
31
Port 4 (P40-P47)
Can be set in input or output mode in units
of 8 bits. In external memory expansion
mode, this port functions as multiplexed
address/data bus (AD0-AD7).
Always functions as multiplexed address/
data bus (AD0-AD7).
Port 5 (P50-P57)
Can be set in input or output mode in
1-bit units. In external memory expansion
mode, this port functions as address bus
(A8-A15).
Always functions as address bus (A8-A15)
Port 9 (P90-P93)
Can be set in input or output mode in
1-bit units. In external memory expansion
mode, P90 outputs RD strobe signal, and
P91 outputs WR strobe signal.
P90 always functions as RD strobe signal
output pin, and P91 always functions as WR
strobe signal output pin. P92 and P93
function as I/O port lines.
Memory expansion
mode register (MM)
Sets port 4 in input or output mode in units
of 8 bits. In external memory expansion
mode, sets memory expansion width of ports
4 and 5.
Always fixed to external memory expansion
mode.
Port 5 mode
register (PM5)
Sets port 5 in input or output mode in
1-bit units.
None
Setting of
MODE0, MODE1
• In ordinary operation mode:
MODE0, 1 = LL
• Always set as follows:
MODE0, 1 = HH
• In ROM-less mode:
MODE0, 1 = HH

Function
Control signal input to set operation mode. With µPD78363A, 78366A, and
78368A MODE0 and MODE1 are usually connected to VSS. With µPD78365A,
MODE0 and MODE1 are always connected to VDD.
System reset input
Crystal oscillator connecting pins for system clock. If a clock is externally
supplied, input it to pin X1. Leave pin X2 open.
A/D converter reference voltage input.
A/D converter analog power supply.
A/D converter GND.
Positive power supply
GND
Internally connected. Connect this pin to VSS.
